LaBeouf: 'Working with Douglas was surreal'

The actor told Us Magazine that their collaboration on the set of director Oliver Stone's latest film was "surreal. It was an out-of-body experience".

"He's got a nice way of easing everybody’s tension," he said. "When you walk onto a set like this, where it’s sacred ground, there’s a legacy at stake. But your mascot puts you at ease."

LaBeouf noted that Douglas was dealing with personal struggles like his son Cameron's drug trial during the movie's production, but he never let his problems affect his performance.

"He is a wolf, and he is a strong man. And I know of his vulnerabilities. When he came to set... he was dealing with a lot, but never was it, 'Woe is me'. Ever."

The star further added that his co-star is likely to go down in history as one of America's greatest actors.

He explained: "They're going to remember him forever. You can't say that about a lot of people. He's an American institution. It's intimidating and incredible and exhilarating and rewarding [to work with him]."
